7 Claims.

This invention relates to, rams and, while notl limited thereto, relates more particularly to rams for use with by-product coke ovens and the like'.

Heretofore, rams such as are used to push coke from by-product coke ovens have been rectangular, or box-like, in cross-section. oftentimes the rams are heated to a high temperature in the coke ovens and, when removed therefrom, their sides frequently were cooled at an uneven rate due to atmospheric conditions. This uneven cooling of the rams caused them to warp and crack so that they required frequent maintenance work. Even though the rams were frequently repaired, their lives were quite short and they tended to bind in the ovens.

One of the objects of this invention is to overcome the aboveand other disadvantages of known types of rams and to provide a sturdy ram ywhich has a long life under sudden and repeated changes in temperature.

'I'he above and further objects will be made apparent by referring to the following description and the accompanying drawing,` in which:

Figure 1 is a plan of the device of the invention, with the center portion thereof being removed;

Figure 2 is an elevation of the device of Figure 1;

Figure 3 is an enlarged elevation of the front end of the device of Figure 1;

Figure 4 is a transverse sectional elevation on line IV-IV of Figure 3; and,

Figure 5 is a transverse sectional elevation on line V-V of Figure 3.

Referring more particularly to the drawing, the q numeral 2 indicates generally a. ram which includes an open truss unit 4. The open truss unit 4 contains an'upper cover-plate 6 and a lower cover-plate 3, both of which extend the length thereof. The cover-plates 6 and 8 are provided with channels I0 and II, respectively, which are secured to the adjacent surfaces thereof, as shown in the accompanying drawing.

In order to hold the cover-plates in spaced relation and form the open truss unit 4, reenforcing means, such as a plurality of channels I2, are secured between the upper cover-plate 6 and the lower cover-plate 8 to form a standard lacing. 'I'he ends of the channels I2 contact and are secured to each other as well as one of the channels I0 and II. The rear portion of the open truss unit 4 is braced by several members I4 which extend perpendicularly between the channels I0 and I I and which have a brace I6 therebetween.

One of the members I4 contacts and braces the channel I2 nearest the rear of the open truss unit 4. A bar I8, or a similar device, protrudes from the open truss unit adjacent the rear thereof to serve as a stop for the open truss unit 4.

A plurality of inverted V-shaped plates 20 may be carried by portions of the` upper surface of the channel II. The legs of the plates 20 are secured to the channel II so that the plates 20 form slanted upper surfaces for portions of the channel Ill. The plates 2i] prevent any objects from remaining on the upper surface of the channel II. l The ram 2 is provided with a short section of H-beam 22, or a similar device, at the front end thereof for the purpose of stiiiening this end and causing the distribution of resisting forces throughout the ram when it is in operation. Strengthening means, such as filler tubes 24, are mounted between the flanges of the H-beam 22 to give the beam additional strength.

A plurality of holes 26 are formed in the upper cover-plate 6 and lower cover-plate Il to facilitate the fastening of driving means to the ram.

Angles 28 are carried by portions'of the open truss unit to aidin the positioning thereof.

A welded construction is contemplated for the ram 2 in order to give it maximum strength with a minimum of weight. The welded construction aids in spacing the channels I2 and allows substantially open portions to be formed between the upper cover-plate 6 and the lower cover-plate 8. These open portions are desirable in that they permit substantially the entire structure of the open truss unit 4 to be subjected to the same atmospheric conditions simultaneously. This tends to insure uniform cooling of the open truss unit 4 and allows the ram to be repeatedly subjected to severe and sudden changes in temperature.

While I have shown and described one specific embodiment of the present invention, it will be understood that I do not wish to be limited eX- actly thereto since various modifications may be made withcutdeparting from the scope of the invention as defined by the following claims.

I claim:

1. A ram comprising an upperr cover-plate, a lower cover-plate, a plurality of lacing members extending diagonally between said cover-plates and forming a unit therewith whereby a substantially open space is formed between said coverplates, V-shaped plates carried by portions of the upper surface of said lower cover-plate to form slanted surfaces therefor, and' means adapted to distribute and transmit large compressive forces associated with one end of said unit.

2. A ram comprising a pair of longitudinally extending spaced-apart channel members, means extending between said members for securely holding them in spaced relation so as to provide an open truss unit, an H-beam member arranged "at one end of said channel members with one of its flanges positioned against the ends there-A of, said H-beam member having av plurality 'of iiller tubes perpendicularly arranged between its flanges, and reenforcing means arranged between the channel members at the opposite end thereof.

3. A ram comprising a pair of longitudinally extending channel members spaced from each other with their channel portions oppositely disposed, a plurality of lacing members extending diagonally between said members for securely holding them in spaced relation so as to provide an open truss unit, a longitudinally extending cover-plate enclosing-each of the channel pory tions of said channel members, said plates extending beyondthe ends of said channel members at least at one end of said truss unit, and a reenforced H-beam member positioned between they extending portions of said cover-plates against the ends 'of said rchannel members so as to distribute and transmit large compressive forces exerted thereon throughout the ram.

4. The combination defined in claim 3, wherein the reenforcingv means comprises an H-beam nmember having a plurality of iller tubes arranged.

between its flanges, said H-beam member arranged between the cover-plates with one of its flanges positioned against the ends of the channel members.

5. A ram comprising a pair of longitudinally extending channel members spaced from each other with their channel portions oppositely disposed, aplurality of lacing members .extending diagonally between said members fo'r securely holding them in spaced relation so as to provide an open truss unit, a longitudinally extending cover-plate enclosing each of the channel portions of said channel members, said plates extending beyond the ends of said channel members at one end of said truss unit, an H-beain member arranged between the extending portions of said cover-plates with one of its llanges positioned against theends of said channel members,

said H-beam member having a plurality of iiller tubes perpendcularlyy arranged between the flanges thereof, and a pair of reenforcing memcover-plate enclosing each of the channel portions of said channel members, said plates extend .ing beyond the ends of said channel members at least 'at one end of said truss unit, and an H-beam member positioned between the extending portions of the cover-plates with one of its flanges positioned against the ends of the channel m'embers, said H-beam member having a plurality' of `filler tubes arrangedl between its anges and adapted to distribute and transmit large compressive forces exerted ,thereon throughout the ram.

`7. A ramr comprising a pair of longitudinally extending channel members spaced from each other with their channel portions oppositely disposed, a plurality of lacing members extending between said channel members for securely holding them in spaced relation so as to provide anopen truss unit, a longitudinally extending coverplate enclosing each of the channel members,

said plates extending beyond the ends of the channel membersat least at oneend of said truss unit and a reenforcing structural member having a plurality of reeniorcing filler tubes associated therewith, said structural member together with the filler tubes positioned between the extending portions ot said cover-plates against the ends of said `channel members so as to distribute and transmit large compressive forces exerted thereon throughout the ram.
